the Function of the Scroll Wheel on the Program panal is so bad

After updating the version, I found that the function of the scroll wheel on the Program Monitor has changed to zooming in and out. This is a completely stupid decision. In most cases, it was just fine for me to use the "Fit" option, and the original function was very handy. Now, after I use the scroll wheel and then press the "~" key, it doesn't show the "Fit" view anymore but a fixed proportion instead. It's so annoying!!!

Why isn't it the case that you hold down the Ctrl key and then roll the scroll wheel to change the proportion?
